A novel bifunctional saponite clay incorporating gadolinium and europium in the inorganic framework was prepared, showing interesting luminescent and paramagnetic properties. Relaxometry and photoluminescence spectroscopy were used to investigate the chemical environment and emission properties of the material, making it an attractive nanoplatform for bimodal diagnostic applications.
A novel bifunctional saponite clay incorporating gadolinium (Gd3+) and europium (Eu3+) in the inorganic framework was prepared by one-pot hydrothermal synthesis. The material exhibited interesting luminescent and paramagnetic features derived from the co-presence of the lanthanide ions in equivalent structural positions. Relaxometry and photoluminescence spectroscopy shed light on the chemical environment surrounding the metal sites, the emission properties of Eu3+, and the dynamics of interactions between Gd3+ and the inner-sphere water placed in the saponite gallery. The optical and paramagnetic properties of this solid make it an attractive nanoplatform for bimodal diagnostic applications.
